It is not planned to raise PoS % in any way, PoS is mainly needed/used for long-time acceptance of the coin and to "keep the chain moving".

Currently everything is working as expected, Stake is quite low but thats okay, PoW has not even ended yet and as soon as we're at a Exchange which our API accepts (C-Cex/Bittrex) the Wallet with Trading Features will be released.
